Bug ID: 521318
Summary: plasmashell freeze after devicenotifier QML binding
loop and Wayland eglSwapBuffers failure (0x300d)
Classification: Plasma
Product: plasmashell
Version First 6.3.6
Reported In:
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: System Tray widget

chat with ai for try to resolve the trouble
DESCRIPTION
While using the system normally, the panel (plasmashell) completely froze and
stopped responding to mouse clicks or shortcuts (though running applications
like Chrome or Konsole continued to work perfectly fine).
According to user logs, the freeze was triggered by a QML binding loop in the
Device Notifier widget (org.kde.plasma.devicenotifier), immediately followed by
a Wayland surface rendering failure (eglSwapBuffers failed with 0x300d). The
plasmashell process became a zombie process, holding the D-Bus name
'org.kde.plasmashell', which prevented spawning a new instance until a hard
'killall -9' was executed.
STEPS TO REPRODUCE
1. Use the system with a Wayland session.
2. Interact with or trigger updates in the System Tray / Device Notifier widget
(e.g., mounting/unmounting drives or general usage causing list refreshes).
3. The panel becomes permanently unresponsive.
OBSERVED RESULT
The taskbar, widgets, and desktop background freeze entirely. Standard
shortcuts to restart the shell like `plasmashell --replace` fail with the
error: "Failed to register name 'org.kde.plasmashell' with DBUS". Only a
forceful `killall -9 plasmashell` frees the bus and allows the shell to
restart.
EXPECTED RESULT
The layout bindings shouldn't loop, and an EGL surface swap failure shouldn't
leave the entire shell process in an unrecoverable deadlock state.
